I just clowned on this platinum Toss so hard, I scouted double gas gateway open initially, then sent an overlord in and scouted blink stalkers (twilight) and no expansion and had such good map control with speedlings that I never even let him get a forward pylon down. Denied his expansion twice, then ran over him with roaches when I had like 3x his supply. Feelsgoodman when you just utterly demolish someone and are in control the entire time!
So there's no one great answer? Playing 2v2s with my friend last night we had a game against a Z+P combo where the Toss went massssss blink stalker. I built mutas and tried to harass wherever the P wasn't while my T partner held them off, but he eventually got so many stalkers that engaging w/ mutas would have been suicidal and we couldn't hold them off with lings + my friend's bio army, so it became a base trade (which we won).
And then they accused us of maphacking. LOLZ
Next question: I've been going ling/bling/muta a lot in HotS so far, which is unfamiliar to me since I used infestors 99% of the time in WoL and almost never went ling heavy in ZvZ. I'm struggling against earlyish (8:00-11:00 maybe?) roach pushes before I have a strong muta count - suggestions?
